Failure of oil extraction in screw press
Spiral oil presses are used to crush soybeans, rapeseeds, cottonseeds, peanuts, and sesame. They are ideal oil extraction machines for small oil mills in rural areas. For various reasons, failures such as less oil or even no oil are sometimes encountered and must be eliminated promptly. 1. Poor oil delivery (1) The oil seams of the crushed bars are too tightly packed with oil slag, crushed pieces or squeezed bars. At this point should clean up the oil residue, or readjust the squeeze bar tightness. If there is oil in the hopper, the material should be stopped, and the oil will be washed out slowly with the cake before continuing its normal work. The oil can also be discharged from the discharge port, and the reel components can be disassembled and then pressed. (2) The oil content of the oil is high, but the cake is too thin so that the oil cannot be discharged from the joint in time and stored in the squeezing hopper or hopper. At this time, the oil seeds with high oil content should be pressed to operate, and the cakes should be thicker, but should be thinner. 2, too much slag (1) the oil is too dry, the end of the crushed from the squeeze seam increased, this time to re-adjust the oil moisture. (2) The oil is too wet to form pressure, and the oil residue cannot be separated. If the oil drain seam is too large at this time, the slag will also be squeezed out from the oil seam. The moisture content of the oil material and the tightness of the pressing bar should be adjusted. 3, the oil rate is low (1) the raw material is too wet or too dry, damp and moldy, the grain is not full, excessive impurities. The oil should be re-cleared or the oil content adjusted. (2) The oil drain seam is blocked by the oil residue. Should be cleared, and according to the level of oil content, adjust the tightness of the pressing bar. (3) Parts wear, wear parts should be replaced. (4) When the cake is too thin or thick, the cake thickness or the oil condition should be adjusted. (5) In the early stage of open pressing, the temperature of the squeezing squeezing is too low and the mill should raise the temperature. 4, the screw shaft is card (1) open squeezed too much at the beginning of the feed, you can use fried oil seeds slowly feed, repeated mill exclusion. (2) During the squeezing process, the inside of the squeezing mash was cut off due to a large amount of feed, and the squeezing smash was blocked by the oil. Therefore, the feeding should be continuous and uniform. In the event of a blockage, the power supply should be turned off immediately, feed must be stopped, and the discharge plate should be opened to exit the screw shaft, remove the oil in the bowl, and then re-press. 5. Other reasons affecting production (1) The cleanliness of the raw materials is not enough, and there are sand and impurities entering the pressing. (2) The screw shaft or cake outlet is not smooth, affect the feed, cake, grinding wheel can be used, can also be chaff and other materials with high coefficient of friction into the cake, add appropriate water, boot, and slowly feed The material will be pressed and the cake will be polished. (3) If the speed of the screw shaft is too high or too low, the speed should be adjusted to meet the requirements. (4) Polish the screw shaft and replace the parts.
